Web19 jan. 2024 · The ImageDataGenerator class in Keras uses this technique to generate randomly rotated images in which the angle can range from 0 degrees to 360 degrees. Our example goes like this – The first step is to import the necessary libraries and load the image. The next step is to convert the image to an array for processing. WebKeras ImageDataGenerator class allows the specification of maximum height and width shifting range. If we set height_shift_range to 200, then the image would shift randomly between 200px up to 200px down. We can also set it to a floating number instead of an integer. A floating number of 0.20 means an image would shift a maximum of 20%.
